ABSTRACT
In this book, we investigate network coding schemes for wireless networks. In Chapter 2, we investigate multiple source communicating with multiple destinations via a common relay. To achieve multiple interpretations at different receivers, we employ nested codes in our proposed system. Besides, an opportunistic scheduling (OS) technique is adopted at the relay to maximize the system capacity. The proposed system model combines the merits of both nested codes and OS. First, we present the detailed coding process of the proposed scheme. Then, we derive the upper bounds on the bit error probability of the schemes with and without OS. Finally, we investigate good codes for our system and carry out simulations to validate the theoretical analysis.
